Research Abstract

Application of low pressure driven membranes (i.e., MF/UF) to drinking water treatment has been receiving a lot of attention and is already being practiced all over the world. The main drawback of this technology is membrane fouling, which is a major obstacle to widespread use of this technology throughout the world. In this study, we newly developed a "carbohydrate adsorbent" by using a plastic polymer having high affinity with hydrophilic organic matters and examined their performance.
A series of batch adsorption experiments showed high performance of the biopolymer adsorbent. It was clarified that the adsorbent have higher affinity for hydrophilic organic matter than for hydrophobic organic matter.
Pretreatment by adsorption of the raw water for membrane filtration 41% prevented the degree of the physically irreversible fouling.
